Teaming 1.0.3.
When checking blog folder for instance, not able to see the thumbnails.
I did check the cache folders and no files are in ..../thumb directories (that could explian we can't see it). I can view html or edit document without any problem.

catalina.out gives me:
"09:10:28,668 ERROR [portal.render_portlet.jsp] com.liferay.portal.SystemException: Unable to retreive buf
fered image from input stream with type na"

but don't know if it is a cause or a consequence ...

Anybody has an idea why ?
